HASP.

Patented Feb. 21, 1911.

1910. Seria1 No. 566,629.

To'all whom it may concern:

Be it known that I, GEORGE W. AYoooK, a citizen of the United States, residing at Murray, in the county of Galloway and State of Kentucky, have invented certain new and useful Improvements in Hasps, and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The objects of the invention are to provide a hasp or fastening for the meeting members of a mold, or similar structure, by which said members will be drawn and held together, and also to provide means whereby the fastening may be readily released.

With these and other incidental objects in view, the invention consists in certain novel features of the device illustrated in the accompanying drawings, which will be hereinafter first fully described and then njore particularly pointed out in the appended c aim.

In the drawings: Figure l is a side view of a mold equipped with my invention; Fig. 2 is a plan view of the same arranged in closed position; Fig. 3 is a detail horizontal section showing the manner in which the fastener draws the meeting members together.

In the accompanying drawings I have shown my invention applied to a mold for forming concrete posts or pillars and consisting of side pieces 1 and end pieces 2 and 8. The ends of the side and end pieces of the mold are hingedly connected at three corners of the mold by suitable hinges 4:.

My improved fastener or hasp is applied to the remaining corner of the mold and consists of a clasp hinge 5, one leaf of which is free of the meeting members and is provided with a slot 6, which is adapted to engage over a staple, or similar fastening device 7, secured to the outer side of the adjacent side piece 1. The end of the hasp is bent outwardly at right-angles so that when the slotted leaf of the hasp is engaged with the staple 7 an aperture will be formed by said right-angularly bent end and the adjacent portions of the staple. Through this aperture is inserted a wedge-shaped fastening pin 8, which, when forced downwardly into the aperture, will bind against one side of the staple and the right-angularly bent end of the hasp thereby drawing the adjacent parts of the mold together and firmly holding the same in closed position.

In order to release the hasp from the staple when the fastening pin is removed, I provide a spring 9, one end of which is secured to the outer surface of one of the sides of the mold in such position that when the hasp is closed upon the staple the spring will be depressed, and, consequently, when the fastening pin is removed, the pressure of the'spring will force the hasp outwardly from its engagement with the staple, thus permitting the mold to be readily opened and removed from the molded object.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that I have provided a very simple and inexpensive hasp by which the meeting members of a mold or similar object may be readily and securely fastened together and easily released when it is necessary to open the structure.

Having thus described my invention what I claim is:

The combination of meeting members, a slotted leaf hinged to and projecting from one member and provided with an outturned free end, a projection on the other member adapted to engage the slot in said leaf, a spring secured to said member adjacent said projection to bear against said slotted leaf, and a wedge inserted between the said projection and the outturned end of the leaf.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

GEORGE WALTER AYGOCK.
